Component: Not specified by the source
Function: only

Attack conditions (Vendor/CNA, CVSS 4.0): Network (remote) · No privileges required · Passive user interaction

What an attacker can do

The source says the sanitizeHttpUrl() function only checks that the URL scheme is http/https and never verifies the host against the server's own origin, so an attacker can supply an arbitrary host. Vendor/CNA’s CVSS 4.0 assessment (base score 9.4/10) rates confidentiality, integrity and availability impact as high.
